Impact of IO TEE in mortality in CABGs patients

TEE in OR was initially applied to assess LV systolic function then remarkably increased use in past two decades.Some indication for IO TEE include: assessment of ventricular systolic and diastolic function ,evaluation of MV ,AV ,TV and PV function ,assessment of associated shunts ,detection of clot or air in heart chambers ,evaluate Ascending and Descending aorta ,grading of atherosclerotic change and protruding plaque in Aortic root and arch.Association of Mitral Regurgitation is the most common combined pathology in CAD patients who need surgical intervention. So definition of Pathology of MR, origin of leak, involved components and also annular sizing are crucial to get the best result of surgery in terms of prognosis and free of symptom survival.TEE also could be useful to define volume status and is the best noninvasive diagnostic tools (instead of invasive measurement of PAWP).So TEE guided hemodynamic intervention is highly recommended.IO TEE also facilitate insertion of catheters in rapidly growing minimal invasive procedures including valve and shunt surgery.In conclusion: Perioperative Echocardiography provide useful information which significantly influences clinical /surgical management to improve outcome of patients.Nowadays IO TEE is the routine diagnostic ,and guiding method in heart surgery.
